delay_parameters

The delay_parameters
directive determines the fill rate and
capacity for each delay pools bucket. Following the pool number, you
must write one, two, or three pairs of numbers. The number of pairs
is the same as the pool's class. A class 1 pool
takes one pair, a class 2 pool takes two pairs, and a class 3 pool
takes three pairs.

Each pair of numbers specifies the fill rate and maximum bucket size.
The fill rate should not be larger than the maximum size. The units
are number of bytes. Thus, if you are thinking in terms of bits per
second, you must divide by 8 to get bytes per second. For example, if
you want to define a bucket that refills at a rate of 100 Kbits/sec,
and holds no more than 300 Kbits (3 seconds) of traffic, you would
write 12500/37500.
